Description

Capsule powder inhalation device
Technical Field
The present invention relates to a capsule powder inhalation device for delivery of a medicament for the treatment of respiratory diseases, such as: asthma and chronic obstructive pulmonary disease in powder form.
Background
Capsule powder inhalers are known in the art, and there are various kinds of capsule powder inhalers. Existing capsule powder inhalers can be divided into three main categories:
the first type: a reservoir type powder inhaler having a reservoir for storing a dose of powder therein and a dosing member for separating the dose of powder from the reservoir on each actuation and then passing the separated powder through a discharge conduit for inhalation into a patient. The disadvantages of such powder inhalants: one, the amount of powder delivered per time is not stable; secondly, the sealing performance of the powder inhaler is poor, so that the powder is easily affected with moisture in a humid environment to influence the expected effect; and thirdly, in the process of separating the powder in the storage, partial powder is remained in the powder inhaler, so that the powder inhaler is polluted and certain harm is caused to a user.
The second type: a multi-dose powder inhaler, wherein the powder is separately stored in advance in blisters on a blister strip, the blisters are evenly distributed on the blister strip, and the blister strip is mounted on a rotating disc inside the powder inhaler; each actuation of the powder inhaler causes a blister to be opened and the powder to be inhaled into the patient through the discharge tube. The powder inhaler better ensures the tightness of the powder; the disadvantages are as follows: firstly, the repeatability is poor, and the difference exists between the front and back delivery of the same powder inhaler to a patient; secondly, the powder inhalator is polluted due to the residual medicine powder inside the powder inhalator, so that certain harm is caused to a user; thirdly, powder residue exists in the bubble cap, so that the performance of the powder does not achieve the expected effect;
in the third category: a single-dose type powder inhaler, wherein powder is separately stored in a single capsule in advance, the capsule is distributed on a capsule plate, a patient firstly takes out the capsule from the capsule plate at the time of using, then the taken-out capsule is put into a capsule chamber 601 of the powder inhaler, the capsule is punctured by pressing a button 300, and the powder is inhaled into the patient through a discharge pipe. The prior products have the following defects: firstly, the existing powder inhaler has poor reliability; for example: firstly, in the puncturing process, the puncturing component is separated from the button 300 component; the button 300 can not be normally pressed and started, so that the powder inhaler can not be normally used; secondly, the powder inhaler can not be cleaned fully, and is easy to cause pollution; thirdly, the use is not humanized enough and is not convenient; the assembly process is complex, the reject ratio is high, and the manufacturing cost is high.
The existing patent numbers: CN1953779B, the patent name suction device, discloses a rotating shaft technology, but its disadvantages are: the way that the suction nozzle 200 is matched with the capsule bin 600 causes the suction nozzle 200 to shake greatly with the capsule bin 600, and the shaking is easy to happen. Sloshing can affect the stability of the dry powder inhaler during use.
